Quebrada Mamilla is a ravine in northern Chile's Antofagasta Region. The ravine is accessed from the Chile Route 1 that unites coastal cities of Iquique and Tocopilla.[1] It is located about 10 km north of Tocopilla.[1] Fourteen archaeological sites have been identified in Quebrada Mamilla.[1] It is thought to have an etymology based on milla, the Mapuche word for gold.[2]
